“…Dense coatings of 20−60 µm thick LSGM can be obtained by atmospheric plasma spraying [54,[59][60][61][62]. In this coating method, the material to be sprayed is heated to a liquid state and transferred to the surface to be treated by means of a plasma steam.…”

This review focuses on Sr/Mg doped lanthanum gallate and its use as a dense electrolyte for medium-temperature solid oxide electrochemical devices. Methods for synthesizing the material are discussed, including techniques that lower the temperature required to attain a single-phase crystalline structure. The effects of secondary phases and grain size on conductivity of ceramics are also investigated. Moreover, the techniques used for compacting electrolyte powder and reducing energy expenses, as well as the impacts of sintering aids on ceramic properties, are analyzed. The potential advantages and disadvantages of the proposed alterations to generate an electrolyte from doped lanthanum gallate are evaluated.

The metal‐supported solid oxide fuel cell (MS‐SOFC) consisting of a porous Ni‐Mo as metal‐support, a La0.75Sr0.25Cr0.5Mn0.5O3–δ (LSCM) as diffusion barrier layer, a nano‐structured Ce0.55La0.45O3–δ (LDC)‐Ni as anode layer, a LDC as anode interlayer, a La0.8Sr0.2Ga0.8Mg0.2O3–δ (LSGM) as electrolyte, a Sm0.15Ce0.85O3–δ (SDC) as cathode interlayer, a 50 wt.% SDC–50 wt.% Sm0.5Sr0.5CoO3–δ (SSC) as composite cathode interlayer and a 25 wt.% SDC–75 wt.% SSC as cathode current collector are prepared by atmospheric plasma spraying (APS). The 25 cm2 cell delivers maximum power densities of 962 and 1,119 mW cm−2 at 700 and 750 °C. The durability, thermal cycling and redox cycling tests of this cell show the cell have good durability, thermal cycle stability and redox stability. The assembled single cell stack of 100 cm2 cell shows electric output powers of 39 W (481 mW cm−2) and 27.4 W (338 mW cm−2) at 750 °C and 700 °C. The long‐term stability test of this single cell stack shows a degradation rate of about 0.77% k−1 h−1 over 1,770 h at 400 mA cm−2 and 700 °C. Furthermore, a 25‐cell MS‐SOFC stack is assembled to evaluate the power performance and it shows a stack power of 829.8 W at 19.85 V and 740 °C.

The metal‐supported intermediate temperature solid oxide fuel cells with a porous nickel substrate, a nano‐structured LDC (Ce0.55La0.45O2–δ)–Ni composite anode, an LDC diffusion barrier layer, an LSGM (La0.8Sr0.2Ga0.8Mg0.2O3–δ) electrolyte, an LSCF (La0.58Sr0.4Co0.2Fe0.8O3–δ)–LSGM composite cathode interlayer and an LSCF cathode current collector are fabricated by atmospheric plasma spraying. Four different plasma spraying powers of 26, 28, 30, and 34 kW are used to fabricate the LSCF–LSGM composite cathode interlayers. Each cell with a prepared LSCF–LSGM composite cathode interlayer has been post‐heat treated at 960 °C for 2 h in air with an applied pressure of 450 g cm–2. The current‐voltage‐power and AC impedance measurements indicate that the LSCF–LSGM composite cathode interlayer formed at 28 kW plasma spraying power has the best power performance and the smallest polarization resistance at temperatures from 600 to 800 °C. The microstructure of the LSCF–LSGM composite cathode interlayer shows to be less dense and composed of smaller dense regions as the plasma spraying power decreases to 28 kW. The durability test of the cell with an optimized LSCF–LSGM composite cathode interlayer gives a degradation rate of 1.1% kh–1 at the 0.3 A cm–2 constant current density and 750 °C test temperature.
